MACHIN E FOR COVERING ELECTRIC CONDUGTO RS.

Patented Apr. 14:, 191%.

To all whom it may concern: I

Be it known that I, EDWARD H. COOK, citizen of the United States, and resident of Wilkes-Barre, in the county of-Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Covering Electric Conductors, of which the following is a specification.

The present invention relates to a machine for covlng a wire or conductor with insulating material, and has more particularly reference to an improved structure for apply-.

ing asbestos or the like to a wire or conductor.

The machine is hereinafter described with especial reference to features of novelty, and

illustrated in the accompanying drawings in.

which,

Figure 1 is a general view showing the complete machine and the location of the several instrumentalities with relation to each other, embodying the invention. Fig. 2 is a plan view of Fig. 1, with certain parts removed. Figs. 1 and 2 are both largely diagrammatic for the sake of "clearness. Fig. 3 is a vertical longitudinal sectional view through the tank for impregnating the covering of the wire, showing also the parts adjacent thereto. Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 3.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates a delivery reel and 2 is the receiving reel, the wire 3 being led from the delivery reel to the receiving reel and passing through the instrumentalities to be hereinafter described' 4 indicates a bath of shellac or other adhesive material, the wire 3 passing under the roller 5 in said bath so as to prepare receiving the fibrous covering. From thence the wire passes through suitable guiding rolls as 6 to the-spinning jenny 7 of any well known construction, which spirally winds the asbestos or other material on the wire.

8 and 9 indicate two brushes whose axes of rotation are substantially at right angles to the axis of the wire and which are driven that of the feeding movement of the wire.

Dies 12, 13, 14, 1 5, are used for compacting rous materlal. One of them has circumferentlal knife edges 17 see Fig. 1,

which extend between the flanges 18 of its companion die, which flanges prevent the" thermore, these dies are preferably heated as by means of the gas pipe 19 having suitable burners as shown, thereby removing the moisture from the asbestos before it is subected to the impregnating compound. W th the construction shown, only one of each pair of dies is heated. These dies are mounted in slidi g boxes 20in a well known manner which may be adjusted by means of the set screws 21.

22 indicates the tank of any suitable construction in which is mounted, or into which extends, a rotatable drum 23. This drum is only partially immersed into the impregnating compound and is adapted to receive the several windings of the wire as shown in Fig. 4 so as to repeatedly subject the covering to the action of the impregnating compound and so as to alternately dip and dry the covering of the wire. This tank is sur-' rounded by an air chamber 24 which extends below the burners 25. At its upper end this air chamber is provided with one or more vent holes 26 covered by a shield 27 which prevents the contents of the tank from reaching the burners. The use of this air chamber insures an even distribution of heat on all sides of the tank, since it is very advantageous that the impregnating compound be maintained at a high degree of temperature. Adjacent to the tank and preferably extending into the plane thereof, is a wiper 28 which here consists of two sheet metal spring arms whose outer ends clasp the wire as it passes in between them. The tension of this wiper inay be regulated by means of the set screws 29.

30 indicates a receptacle or hopper containing powdered soapstone or some similar material which is discharged upon the passing wire, thereby tending to additionally dry it and give it a smooth finish, preventv with this spur are the guide rollers 32, 33, 34 and 35.

31 indicates a pair of finishing rolls through which the wire passes after having been dusted by the soapstone and from which the wire finally passes to the receiv-' ing reel 2. The impregnating compound is preferably an asphaltum compound a hydro-carbon base, but it may be any standard compound now. in use, having the properties of making the asbestos water and acid proof. Interposed at suitable points The gearing used in the present instance is as follows: 36 indicates a main shaft to which motion is imparted in any suitable manner as by means of the cone pulley 37. The delivery reel is operated by means of the spur gears 38 and 39, the latter of which is mounted on the shaft 40 having at its other end the bevel gear 41 meshing with the bevel gear 42 on the main shaft. The spinning jenny is operated by means of a train of spur gears indicated by 43, 44 and 45. Each pair of brushes is operated from a shaft 46 which receives its motion from the main shaft by means of the bevel gears 47 and 48. Mounted on one of the shafts 46' is a spur gear 49 meshing with the spur gear 50 mounted on the stud 51. Moving gear 50 is a similar gear 52 which transmits its motion to the inion 53 meshing with the gear 54, with which latter moves the pinion 55 meshing with the gear 56 on the stud 57 which carries one of the brushes. The otherof the brushes is operated from the gear 52 through the intermediate gear 58, pinion 59 and gear 60' on the stud 61. The foregoing describes the driving connections for the vertically rotating brushes. The horizontally rotatin brushes are driven from the other shaft 46 i y means of bevel gears 62 and 63, the ear 63 being mounted on the stud 64 0 one of the brushes, said stud carrying a spur gear meshing with a similar spur gear 65 on the stud 66 of the other brush. The horizontally rotating dies are driven by means of a train of spur gears 67 68 and 69, the latter of which is mounted on the counter-shaft 70 which counter-shaft is provided with'a plurality of bevel gears 71 meshing with corresponding bevel gears 72 on the shafts 73, which shafts 73 carry each a spurxgear having.

- shafts 83 have the spur gears 98, the pulley 94 moving with the If desired, the guide 74 meshing with 'a correspgnding spur gear the shafts 76.

The vertically rotatable rolls are driven from a train ofspur gears 77, 78 and 79 to the counter-shaft '80, which counter-shaft is provided with aseries of bevel gears 81 meshing with the bevel gears 82 mounted on the shafts 83 of the upper dies.

84 which mesh with corresponding spur rs 85 on the shaft with the'lower dies. The rotatable drum 23 in the tank is operated from the pinion 86 whichmeshes with the gear 87 on the shaftof the drum. The pinion 86-is operated by means of the friction pulleys 88 and 89 and belt 90 from the shaft'--91, which latter receives its motion from the main shaft by means of'the bevel gears 92. The receiving reel is driven'by means of pulleys 93, and 96 pulley 89. rolls may be driven positively by means of bevel gears 99 operating shaft 100 from which motion is transferred to the guide rolls by means of spur gears 101 and 102.

What is claimed is v 1. In a machine for covering electrical conductors, the combination with means for applying flocculent material to a wire, of a tank for containing a liquid impregnating material, a rotary drum, whose lower portion lies in the said tank, a wiper comprising spring. armswhose free ends press together so as to work in contact with the wire covering, said wiper being arranged on the delivery side of the drum, as described.

The said 7 e and belts 97 and 2. In a machine for covering electrical conductors,- the combination with means for applying flocculent material to a wire, a tank for containing a liquid impregnating material, an air chamber inclosing the said tank save at the top and provided with vent holes, and burners arranged in the air chamber and under the bottom of the tank, as described.
